Thanks in advance
If using Illustrator, it’s important to use the keyboard shortcuts so you’re not diving into the menu between points - clicking a menu or tool will cause you to switch out of ‘drawing’ mode forcing you to awkwardly restart your line from the last point you made.
Important keys: alt/option, ctrl, space for moving around the scene without breaking your line, shift, and A and V for toggling between selection types (point/line). Play around with alt and ctrl keys while dragging handles - you can create corners by ‘breaking’ the straight bezier handle that controls the curve shape.
Good luck. Find an interesting piece of clip art and have at it. Option clicking a point with handles will turn it into a corner. Option clicking that same point while dragging out will recreate the bezier handle.
Photoshop’s path tool works the same way with the same shortcuts. However it’s primarily used for making a selection and not for drawing per se. You can export paths out of Photoshop but I highly recommend using Illustrator and not Photoshop for learning the pen tool.
Inkscape, fresco, and Concepts all come to mind.
You can't magically be good at vector art (or raster art just because you bought Photoshop, or creative writing just because you bought Word or some other desktop publishing software) without proper training. Art training teaches you the non-technical aesthetics and artistic skills to know what to do with Illustrator or vector software or raster software, and ONLY THEN will what you do technically with such software packages to achieve your goals.
You can generate basic curves here to practise tracing them.
